I'm thinking of a device that would rotate an engine to exact degrees for tuning and valve adjustments. This device would have a removable coupling to attach to the crank or flywheel, and an electronic system would roll the engine over to specified targets.
It would have the capability to precisely determine #1 top dead center, so it would "zero". The use of electronic controls would regulate an electric motor to turn the engine to the exact degree.
I have a bunch of ideas on different ways to accomplish this. What do you guys think?
Has this been done? Is it available? What challenges would it face? What features should be incorporated?
